public class SimpleImageScaler extends Object implements IImageScaler
Basic implementation ofIImageScaler
. A n-by-n source region is transformed to 1 output pixel by picking the upper-left-most of the n-by-n pixels.

downsample
public byte[] downsample(byte[] srcImage, int width, int height, double scaleFactor, int bytesPerPixel, boolean littleEndian, boolean floatingPoint, int channels, boolean interleaved)
Description copied from interface:IImageScaler
Downsamples the given image.- Specified by:
downsample
in interfaceIImageScaler
- Parameters:
srcImage
- a byte array representing the image to be downsampledwidth
- the width in pixels of the source imageheight
- the height in pixels of the source imagescaleFactor
- the value used to calculate the downsampled width and height; expected to be greater than 1bytesPerPixel
- the number of bytes in one pixel (usually 1, 2, 4, or 8)littleEndian
- true if bytes in a pixel are stored in little endian orderfloatingPoint
- true if the pixels should be interpreted as float or double instead of uint32/uint64channels
- the number of RGB channels included in srcImageinterleaved
- true if the RGB channels are stored in interleaved order (RGBRGBRGB... and not RRR...GGG...BBB)- Returns:
- the downsampled image
